RESUMEN

BACKGROUND: Although extracorporeal life support (ECLS) can provide emergency systemic perfusion for acute fulminant myocarditis (AFM), the mortality rate remains extremely high, especially in those undergoing extracorporeal cardiopulmonary resuscitation (ECPR). Temporary ventricular assist device (VAD) can provide a more physiological blood flow direction and better subsequent organ perfusion than ECLS. We investigated temporary VAD efficacy in ECPR-revived AFM patients. METHODS: During January 2012-May 2019, we retrospectively recruited 22 AFM patients with hemodynamic collapse and ECPR; 11 underwent ECLS only and 11 underwent additional VAD support after ECLS. Systemic perfusion was compared via laboratory biochemistry at post-ECPR days 2 (D2) and 4 (D4). Consciousness and cardiac function were assessed through the Glasgow Coma Scale (GCS) and echocardiography, respectively. All major complications and causes of mortality were recorded; 30-day survival was analyzed and risk factors were predicted. RESULTS: The VAD group had significantly better hemodynamic improvement; more inotropes being tapered at D2 and D4; better data representative of systemic perfusion, including albumin, pH, bicarbonate, and lactate levels at D4; and better 30-day survival (72.7% vs. 27.2%, p = 0.033). The causes of mortality included central failure, multiple organ failure, and bacteremia with sepsis. The risk factors included lethal dysrhythmia before ECLS, GCS <5 at D2, and elevated cardiac enzymes at D4. CONCLUSION: For AFM patients, temporary VAD could provide better systemic perfusion and organ preservation than ECLS. VAD had better survival, including improved recovery and successful transplantation. Hence, temporary VAD should be considered if ECLS cannot revive the sustained cardiogenic shock.

RESUMEN

BACKGROUND: Patients with cardiogenic shock have a high risk of mortality. Intravenous levosimendan can provide pharmacologic inotrope support. OBJECTIVES: We aimed to investigate the effect of levosimendan in patients with extremely severe cardiogenic shock and low Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) score with or without mechanical circulatory support. METHODS: From January 2017 to May 2019, 24 patients with INTERMACS 1-4 were enrolled in this retrospective study. All patients had systemic malperfusion and were treated with levosimendan. Biochemistry data related to systemic perfusion were recorded and compared before and at 24 and 72 hours after levosimendan administration. Echocardiography and Kansas City Cardiomyopathy Questionnaire (KCCQ) were completed 2 months later to assess left ventricular ejection fraction (LVEF) and quality of life (QoL), respectively. RESULTS: Arterial pressure and heart rate did not significantly differ before and after levosimendan administration. Atrial fibrillation and ventricular premature complex increased without significance. The dose of inotropes could be significantly tapered down. There were no significant differences in blood urea nitrogen, creatinine, and lactate levels. Urine output significantly increased (p = 0.018), and liver-related enzymes improved but without significance. B-type natriuretic peptide significantly decreased (p = 0.007) at 24 hours after levosimendan administration. Echocardiography showed significantly improved LVEF 2 months later (22.43 ± 8.13% to 35.87 ± 13.4%, p = 0.001). KCCQ showed significantly improved physical activity and greater relief of symptoms (p = 0.003). The survival-to-discharge rate was 75%. CONCLUSIONS: We observed a decrease in B-type natriuretic peptide, better urine output, and alleviated hepatic injury in the levosimendan group. Most patients who survived without transplantation had significantly improved LVEF and better QoL after levosimendan administration.

RESUMEN

AIMS: To explore the child-rearing experiences of immigrant mothers and their concerns about children's home environments in the contexts of transnational marriage families and non-native culture. BACKGROUND: Immigrant mothers are often disadvantaged by a relative lack of information on and access to children's healthcare, but little research exists on the experiences of mothers in transnational marriage families as they attempt to provide a secure home environment while navigate an unfamiliar culture. DESIGN: A descriptive phenomenological research design based on intuition was employed to explore immigrant mothers' unique lived reality through their subjective experiences and perceptions. METHODS: Semi-structured interviews with 15 immigrant mothers from 15 transnational marriage families were conducted between May 2016-February 2017. Narratives were analyzed using the descriptive phenomenological method because it permits systematic discovery of the lived experiences from the perspective of the study's participants. RESULTS: Three major themes were identified: (a) striving to maintain a secure home for children; (b) suffering and struggling with difficulties; and (c) trying to overcome difficulties and build an adequate family environment. The essential, prevailing concept of immigrant mothers' experience in child-rearing was identified as 'Where my child is, is home.' CONCLUSION: Immigrant mothers bond emotionally and physically to their new land via their children. Their child-raising experiences are interwoven with their roles in their new familial and cultural homes. IMPACT: Immigrant brides often become mothers soon after marrying to continue their husbands' family line. Understanding their unique child-rearing experiences and challenges in providing a secure home in a non-native culture will help nurses provide effective care. Study results will benefit paediatric/family nurses in any setting where care for transnational marriage families is provided, those families themselves, public policymakers and future researchers.

RESUMEN

North America experienced life-threatening outbreaks of enterovirus D68 (EV-D68) in 2014. We retrospectively detected EV-D68 from a child with Wilson's disease in 2008 in Taiwan. After comparing this EV-D68/Taiwan/2008 strain with EV-D68 genomes obtained from the public domain, it was classified as genome type 1-B; it is phylogenetically related to the predominant EV-D68 viruses that circulated in 2009 in Vietnam. It is necessary to strengthen EV-D68 detection globally, including in children with acute liver failure. Moreover, harmonization of genomic analysis of EV-D68 is desirable to understand global evolution of EV-D68.

RESUMEN

BACKGROUND: Traditional Chinese medicine (TCM) has been used by Chinese patients and in many other countries worldwide. However, epidemiological reports and prescription patterns on children are few. METHODS: A cohort of 178,617 children aged 18 and under from one million randomly sampled cases of the National Health Insurance Research Database was analyzed for TCM prescription patterns. SAS 9.1 was applied and descriptive medicine utilization patterns were presented. RESULTS: The cohort included 112,889 children treated by TCM, with adolescents (12- to 18-year-olds) as the largest group. In the children's TCM outpatient visits, Chinese herbal remedies were the main treatment. The top three categories of diseases treated with Chinese herbal remedies were respiratory system; symptoms, signs, and ill-defined conditions; and digestive system. The top three categories using acupuncture were: injury and poisoning, diseases of the musculoskeletal system and connective tissue, and diseases of the respiratory system. Of the top ten herbal medicines prescribed by TCM physicians, the top nine herbal formulae and the top ten single herbs were associated with diseases of the respiratory system. CONCLUSION: This study identified patterns of TCM prescriptions for children and common disease categories treated with TCM. The results provide a useful reference for health policy makers and for those who consider the usage of TCM for children.

RESUMEN

BACKGROUND: Streptococcus agalactiae (GBS) is a common pathogen to infect newborn, woman, the elderly, and immuno-compromised human and fish. 37 fish isolates and 554 human isolates of the GBS in 2007-2012 were investigated in serotypes, antibiotic susceptibility, genetic difference and pathogenicity to tilapia. RESULTS: PCR serotyping determined serotype Ia for all fish GBS isolates and only in 3.2 % (3-4.2 %) human isolates. For fish isolates, all consisted a plasmid less than 6 kb and belonged to ST7 type, which includes mainly pulsotypes I and Ia, with a difference in a deletion at the largest DNA fragment. These fish isolates were susceptible to all antimicrobials tested in 2007 and increased in non-susceptibility to penicillin, and resistance to clindamycin and ceftriaxone in 2011. Differing in pulsotype and lacking plasmid from fish isolates, human serotype Ia isolates were separated into eight pulsotypes II-IX. Main clone ST23 included pulsotypes II and IIa (50 %) and ST483 consisted of pulsotype III. Human serotype Ia isolates were all susceptible to ceftriaxone and penicillin and few were resistant to erythromycin, azithromycin, clindamycin, levofloxacin and moxifloxacine with the resistant rate of 20 % or less. Using tilapia to analyze the pathogenesis, fish isolates could cause more severe symptoms, including hemorrhage of the pectoral fin, hemorrhage of the gill, and viscous black and common scites, and mortality (>95 % for pulsotype I) than the human isolates (<30 %); however, the fish pulostype Ia isolate 912 with deletion caused less symptoms and the lowest mortality (<50 %) than pulsotype I isolates. CONCLUSION: Genetic, pathogenic, and antimicrobial differences demonstrate diverse origin of human and fish serotype Ia isolates. The pulsotype Ia of fish serotype Ia isolates may be used as vaccine strains to prevent the GBS infection in fish.

RESUMEN

Background/Aims: Nonalcoholic fatty liver disease (NAFLD) is a common disease with severe inflammatory processes associated with numerous gastrointestinal diseases, such as inflammatory bowel disease (IBD). Therefore, we investigated the relationship between NAFLD and IBD and the possible risk factors associated with the diagnosis of IBD. Methods: This longitudinal nationwide cohort study investigated the risk of IBD in patients with NAFLD alone. General characteristics, comorbidities, and incidence of IBD were also compared. Results: Patients diagnosed with NAFLD had a significant risk of developing IBD compared to control individuals, who were associated with a 2.245-fold risk of the diagnosis of IBD and a 2.260- and 2.231-fold of increased diagnosis of ulcerative colitis and Crohn's disease, respectively (P< 0.001). The cumulative risk of IBD increased annually during the follow-up of patients with NAFLD (P< 0.001). Conclusions: Our results emphasize that NAFLD significantly impacts its incidence in patients with NAFLD. If patients with NAFLD present with risk factors, such as diabetes mellitus and dyslipidemia, these conditions should be properly treated with regular follow-ups. Furthermore, we believe that these causes may be associated with the second peak of IBD.

RESUMEN

Colorectal cancer (CRC) and nonalcoholic fatty liver disease (NAFLD) have high prevalence rates and place a considerable burden on the health-care industry. The association between both diseases is controversial. Our aim was to examine the association between NAFLD and CRC. Using data extracted from the Taiwan National Health Insurance Research Database (NHIRD) from 2000 to 2015, we enrolled 60 298 patients with NAFLD. Of these, 52,986 met the inclusion criteria. A comparison group was selected using 4-fold propensity score matching by age, sex, and year of index date. The primary outcome was the cumulative incidence of CRC in patients with NAFLD. Over a mean follow-up period of 8.5 years, 160 new cases of CRC were identified. The incidence rate of CRC was higher in the NAFLD group (12.23 per 100,000 person-years) than in the comparison cohort (6.0 per 100,000 person-years). Cox proportional hazards regression analysis revealed that the adjusted hazard ratio (HR) of CRC was 1.259 in the study group (95% confidence interval [CI]: 1.047-1.486, P = .003). Using Kaplan-Meier analysis, we ascertained that the cumulative incidence of CRC was significantly high in the NAFLD group. Patients older than 50 years, with diabetes mellitus (DM), and with chronic liver disease also exhibited a high risk of CRC. NAFLD was associated with a high risk of CRC. CRC occurs more frequently in patients with NAFLD aged between 50 and 59 years and those older than 60 years with comorbidities, including DM and chronic liver disease. Physicians should consider the subsequent risk of CRC when treating patients with NAFLD.

RESUMEN

Neonatal meningitis Escherichia coli (NMEC) is the most common Gram-negative organism that is associated with neonatal meningitis, which usually develops as a result of hematogenous spread of the bacteria. There are two key pathogenesis processes for NMEC to penetrate into the brain, the essential step for the development of E. coli meningitis: a high-level bacteremia and traversal of the blood-brain barrier (BBB). Our previous study has shown that the bacterial outer membrane protein NlpI contributes to NMEC binding to and invasion of brain microvascular endothelial cells, the major component cells of the BBB, suggesting a role for NlpI in NMEC crossing of the BBB. In this study, we showed that NlpI is involved in inducing a high level of bacteremia. In addition, NlpI contributed to the recruitment of the complement regulator C4bp to the surface of NMEC to evade serum killing, which is mediated by the classical complement pathway. NlpI may be involved in the interaction between C4bp and OmpA, which is an outer membrane protein that directly interacts with C4bp on the bacterial surface. The involvement of NlpI in two key pathogenesis processes of NMEC meningitis may make this bacterial factor a potential target for prevention and therapy of E. coli meningitis.

RESUMEN

Escherichia coli is a common Gram-negative organism that causes bacteremia. Prc, a bacterial periplasmic protease, and its homologues are known to be involved in the pathogenesis of Gram-negative bacterial infections. The present study examined the role of Prc in E. coli bacteremia and characterized the ability of the prc mutant of the pathogenic E. coli strain RS218 to cause bacteremia and survive in human serum. The prc mutant of RS218 exhibited a decreased ability to cause a high level of bacteremia and was more sensitive to serum killing than strain RS218. This sensitivity was due to the mutant's decreased ability to avoid the activation of the antibody-dependent and -independent classical complement cascades as well as its decreased resistance to killing mediated by the membrane attack complex, the end product of complement system activation. The demonstration of Prc in the evasion of classical complement-mediated serum killing of pathogenic E. coli makes this factor a potential target for the development of therapeutic and preventive measures against E. coli bacteremia.

RESUMEN

Streptococcus agalactiae (GBS) can infect newborns, pregnant women and immunocompromised or elderly people. This study aimed to investigate differences in three pilus genes and virulence genes pavA, cfb, rib and scpB and changes in predominant serotypes III, V and VI from 2008 to 2012. The susceptibilities to penicillin, ceftriaxone, azithromycin, erythromycin, clindamycin, levofloxacin and moxifloxacin of 145 GBS strains of serotype III, V and VI strains from 2008 and 2012 were determined using disc diffusion method. PCR identification of ST-17, the pilus genes and virulence genes; multilocus sequence typing (MLST); and conserved domain and phylogenetic analysis of scpB-1 and scpB-2 proteins were performed. A dramatic number reduction was observed in serotype V, not III and V, from 2008 to 2012. The rate of resistance to azithromycin, clindamycin and erythromycin was the highest in serotype V. ST-17 was only found in serotype III with pilus genes PI-1+PI-2b. The major pilus genotype was PI-1+PI-2a. Serotype V without the rib gene was reduced in number between two studied years. Compared to scpB-1,&nbsp;scpB-2 had a 128-bp deletion in a PA C5a-like peptidase domain and putative integrin-binding motif RGD. In conclusion, reduction in serotype V may be due to presence of scpB-2 or lack of genes scpB and rib.

RESUMEN

Background: The extracorporeal life support (ECLS) and temporary bilateral ventricular assist device (t-BiVAD) are commonly applied in patients with cardiogenic shock. Prolonged cardiopulmonary resuscitation (CPR) has poor prognosis. Herein, we report our findings on a combined ECLS and t-BiVAD approach to salvage cardiogenic-shock patients with CPR for more than one hour. Methods: Fifty-nine patients with prolonged CPR and rescued by ECLS and subsequent t-BiVAD were retrospectively collected between January 2015 and December 2019. Primary diagnoses included ischemic, dilated cardiomyopathy, acute myocardial infarction, post-cardiotomy syndrome, and fulminant myocarditis. The mean LVEF was 16.9% ± 6.56% before t-BiVAD. The median ECLS-to-VAD interval is 26 h. Results: A total of 26 patients (44%) survived to weaning, including 13 (22%) bridged to recovery, and 13 (22%) bridged to transplantation. Survivors to discharge demonstrated better systemic perfusion and hemodynamics than non-survivors. The CentriMag-related complications included bleeding (n = 22, 37.2%), thromboembolism (n = 5, 8.4%), and infection (n = 4, 6.7%). The risk factors of mortality included Glasgow Coma Scale (Motor + Eye) ≤ 5, and lactate ≥ 8 mmol/L at POD-1, persistent ventricular rhythm or asystole, and total bilirubin ≥ 6 mg/dL at POD-3. Mortality factors included septic shock (n = 11, 18.6%), central failure (n = 10, 16.9%), and multiple organ failure (n = 12, 20.3%). Conclusions: Combined ECLS and t-BiVAD could be a salvage treatment for patients with severe cardiogenic shock, especially for those already having prolonged CPR. This combination can correct organ malperfusion and allow sufficient time to bridge patients to recovery and heart transplantation, especially in Asia, where donation rates are low, as well as intracorporeal VAD or total artificial heart being seldom available.

RESUMEN

BACKGROUND: A pediatric nursing practicum is essential in equipping students with basic knowledge of theory, professional attitudes, and skills for the clinical setting. However, students often face multiple challenges in the practicum due to gaps between theory and practice. PURPOSE: To describe nursing students' first-time experiences in pediatric clinical practice in Taiwan. METHODS: A phenomenological approach with purposive sampling was used. Twenty participants were interviewed individually, in person, within a month of completion of a pediatric nursing practicum. Interviews were semi-structured and digitally recorded. Data analysis followed Colaizzi's methods; epochs (bracketing) focused analysis on students' experiences and maintained objectivity. FINDINGS: Three themes and related subthemes emerged: (a) orienting to the pediatric unit (becoming familiar with common treatments and surroundings in the pediatric unit; recognizing people in the unit); (b) encountering challenges in pediatric and family-centered care (navigating communication between child and families; student nurse-patient relationships: maintaining a good rapport with children and their families; being prepared for quick role changes); (c) translating knowledge into clinical practice thoughtfully (providing desirable and correct responses for children and their families; providing a safe and friendly environment for children and their families). CONCLUSIONS: Student nurses engaged in a variety of care practices necessitated by patients' differing ages, developmental levels, and family needs. Ensuring students' successful completion of the demanding pediatric practicum, including innovative communication, technical skills, and role transitions, is challenging yet achievable. CLINICAL RELEVANCE: Gaining a fuller understanding of nursing students' experiences in the pediatric nursing practicum can assist nursing professionals in preparing students to provide competent care for children and their families.

RESUMEN

In this work, InGaN/GaN multiple-quantum-wells light-emitting diodes with and without graphene transparent conductive electrodes are studied with current-voltage, electroluminescence, and time-resolved electroluminescence (TREL) measurements. The results demonstrate that the applications of graphene electrodes on LED devices will spread injection carriers more uniformly into the active region and therefore result in a larger current density, broader luminescence area, and stronger EL intensity. In addition, the TREL data will be further analyzed by employing a 2-N theoretical model of carrier transport, capture, and escape processes. The combined experimental and theoretical results clearly indicate that those LEDs with graphene transparent conductive electrodes at p-junctions will have a shorter hole transport time along the lateral direction and thus a more efficient current spreading and a larger luminescence area. In addition, a shorter hole transport time will also expedite hole capture processes and result in a shorter capture time and better light emitting efficiency. Furthermore, as more carrier injected into the active regions of LEDs, thanks to graphene transparent conductive electrodes, excessive carriers need more time to proceed carrier recombination processes in QWs and result in a longer carrier recombination time. In short, the LED samples, with the help of graphene electrodes, are shown to have a better carrier transport efficiency, better carrier capture efficiency, and more electron-hole recombination. These research results provide important information for the carrier transport, carrier capture, and recombination processes in InGaN/GaN MQW LEDs with graphene transparent conductive electrodes.

RESUMEN

A 28-year-old man who had a history of type 1 diabetes mellitus with poor medication compliance was referred to the emergency department of our institute with suspected diabetic ketoacidosis. The patient developed sudden cardiac arrest following continuous insulin administration. Laboratory data revealed severe hypokalaemia. Cardiopulmonary resuscitation was performed immediately for 63 minutes. Although his spontaneous circulation resumed, the haemodynamics remained unstable. Peripheral extracorporeal membrane oxygenation was therefore employed for mechanical circulatory support. Echocardiography under these conditions revealed generalised hypokinesia of the bilateral ventricles. The left ventricular ejection fraction was only 10-15%. The chest film revealed bilateral pulmonary congestion. The patient developed multiple organ dysfunction, including acute kidney injury, liver congestion and persistent pulmonary oedema, although the hypokalaemia resolved. A temporary bilateral ventricular assist device (Bi-VAD) was used for superior systemic perfusion and unloading of the bilateral ventricles after 16 hours of extracorporeal membrane oxygenation support. After the start of maintenance using the Bi-VAD, extracorporeal membrane oxygenation was discontinued and the inotropic agents were tapered down immediately. Subsequently, the haemodynamics stabilised. All the visceral organs were well perfused with Bi-VAD support. Subsequent echocardiography demonstrated recovery from the myocardial stunning, with the left ventricular ejection fraction returning to 50-60%. The Bi-VAD was gradually weaned and successfully removed 12 days after implantation. The patient had an uneventful recovery and was discharged without organ injury. Over one year of follow up in our out-patient clinic, adequate cardiac function and improved diabetes control were found.

RESUMEN

Growing cultural diversity among immigrants has challenged health care practice in Taiwan. This study used mixed methods to evaluate how the implementation of a course on cultural competence embedded in a nursing course affected nursing students' perceptions of their cultural care competency. An evaluation survey with a quantitative questionnaire comprising pre- and post-test measures of self-perceived cultural care competency was implemented for 48 participants at the commencement and completion of the course. A focus group interview (n = 10) was conducted and a thematic approach applied to analyze qualitative data. The results found a significant improvement in self-perceived cultural care competency (t = 7.15, p < 0.001). Two themes emerged from the qualitative analysis: (1) the thought-provoking nature of the course and (2) appreciation for the multiple learning strategies of the course.

RESUMEN

BACKGROUND: Clinical practice is an essential component of nursing students' preparation for applying theoretical knowledge in a real-life setting. However, students often experience clinical practice as extremely stressful, which may disrupt their clinical performance, impact the quality of patient care they provide as well as their own physical and psychological health, and hinder their continuation into nursing careers. Resilience, understood as the capability to overcome challenges, is critical for these students. PURPOSE: To develop and implement a resilience enhancement (RE)-based project for Taiwanese nursing students during their Last Mile practicum. DESIGN AND METHODS: A participatory action research (PAR) approach was used in which ongoing planning, action, and reflection informed real-time progress. Twenty-eight nursing students in clinical practice participated in the study. A six-workshop RE project was completed over the course of two months. Evaluation methods involved group discussion, individual interviews, and reflective diaries. Content analysis was applied to the data. RESULTS: Through a PAR-based project, participants achieved positive results. Three outcome themes were identified: Increasing self-exploration, Furthering confidence and competency, and Constructing resilience. CONCLUSIONS: The PAR-based RE project helped students to develop resilience by enhancing their nursing knowledge and skills and practicing positive thinking and behavior. CLINICAL RELEVANCE: The findings can be a reference for nursing educators in designing RE programs for students during clinical practice to increase their professional competence and provide psychological supports.
